    en.wikipedia.org/wiki/Water_testing

    Water testing being conducted at a treatment facility in Broken Bow, Oklahoma. Water testing is a broad description for various procedures used to analyze water quality. Millions of water quality tests are carried out daily to fulfill regulatory requirements and to maintain safety. [1] Testing may be performed to evaluate:

  3. Levelized cost of water - Wikipedia

    en.wikipedia.org/wiki/Levelized_cost_of_water

    The levelized cost of water (LCOW or LCW) is the "cost per unit volume of product water produced by a water treatment process or service". It is a measure of efficiency, with lower values representing more efficient methods. LCW can refer to drinking water for human consumption or water for irrigation. [1]

  4. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    Hard water can cause scale buildup in pipes, valves, and filters, reducing performance and adding to system maintenance costs. These effects can be seen in aquariums, spas, swimming pools, and reverse osmosis water treatment systems. Typically, total dissolved solids are tested frequently in these applications, and filtration membranes are ...

  5. Biochemical oxygen demand - Wikipedia

  9. Chemical plant cost indexes - Wikipedia

    en.wikipedia.org/wiki/Chemical_plant_cost_indexes

    Chemical plant cost indexes are dimensionless numbers employed to updating capital cost required to erect a chemical plant from a past date to a later time, following changes in the value of money due to inflation and deflation. Since, at any given time, the number of chemical plants is insufficient to use in a preliminary or predesign estimate ...
